The LTC4306CUFD#TRPBF is an integrated circuit (IC) component manufactured by Linear Technology. It is a hot-swappable, 2-wire bus buffer that is designed to provide a level translation and buffering between different voltage levels on the I2C bus.
One of the key features of the LTC4306CUFD#TRPBF is its ability to provide bidirectional buffering and level shifting between low voltage (LV) and high voltage (HV) sides of the I2C bus. This makes it suitable for interfacing devices that operate at different voltage levels, eliminating the need for external level shifting circuits. The voltage on the LV side can range from 1.8V to 5V, while on the HV side it can be between 2.5V and 5.5V.
Another notable feature of this IC is its fast automatic bus buffer turn-off feature. This allows the LTC4306CUFD#TRPBF to disable its buffer during a fault condition, such as bus contention or excessive capacitive loading, ensuring data integrity and protecting the connected devices. The IC also provides high impedance on both the LV and HV sides when the Vcc or HV power supplies are not present, further improving bus reliability.
The LTC4306CUFD#TRPBF offers a high-speed mode for communication speeds up to 400kHz, making it suitable for fast and high-performance applications
